14、) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrica

15、l and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technica

16、l committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organiza

17、tion for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical co

18、mmittee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications

19、 is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national an

20、d regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services a

21、nd, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants o

22、r agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, us

23、e of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that

24、some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may

25、propose the publication of a technical specification when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possi

26、bility of an agreement on an International Standard. Technical specifications are subject to review within three years of publication to decide whether they can be transformed into International Standards. IEC 62257-1, which is a technical specification, has been prepared by IEC technical committee

27、82: Solar photovoltaic energy systems. It was developed in cooperation with other IEC technical committees and subcommittees dealing with renewable energies and related matters, namely IEC technical committee 21 (Secondary cells and batteries), subcommittee PD IEC/TS 62257-1:2015 4 IEC TS 62257-1:20

28、15 IEC 2015 21A (Secondary cells and batteries containing alkaline or other non-acid electrolytes), IEC technical committee 64 (Electrical installations and protection against electric shock), IEC technical committee 88 (Wind turbines). This third edition cancels and replaces the second edition issu

29、ed in 2013. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: Redefine the maximum AC voltage from 500 Va.c. to 1 000 Va.c., the maximum DC voltage from 750 Vd.c. to 1 500 Vd.c. and removal of the limitation of 100 kVA system size. He

PD IEC/TS 62257-1:2015IEC TS 62257-1:2015 IEC 2015 5 INTRODUCTION Rural electrification is one of the predominant policy actions designed to increase the well- be

36、ing of rural populations together with access to clean water, improved healthcare, education, personal advancement and economic development. Several strategies can be adopted to implement rural electrification. Rural electrification can be completed through connection to a national or regional elect

37、rification grid. The IEC 62257 series applies to cases where the grid is too far away (too costly) or the individual demand centres are too small to make grid access economic, where autonomous power systems may be used to supply these services. This series IEC 62257 provides technical specifications

38、 to different players involved in rural electrification projects (such as project developers, project implementers, installers, etc.) for the setting up of renewable energy and hybrid systems with AC voltage below 1 000 Vac and DC voltage below 1 500 Vdc. These specifications are recommendations: a)

39、 to choose the right system for the right place, b) to design the system, c) to operate and maintain the system. The specifications focus on rural electrification concentrating on, but not specific to, developing countries. They must not be considered as all inclusive to rural electrification. That

40、means that they could be used for rural electrification or electrification of remote sites in developed countries also. They try to promote the use of renewable energies in rural areas, but they do not deal with clean mechanisms development at this time (CO 2emission, carbon credit, etc.) Further de

41、velopments in this field could be introduced in future steps. This consistent set of documents is best considered as a whole with different parts corresponding to items for safety, sustainability of systems and at the lowest life cycle cost as possible. One of the main objectives is to provide the m

42、inimum sufficient requirements, relevant to the field of application, that is: renewable energy and hybrid off-grid systems.

43、57 series and rural electrification 1 Scope This part of IEC 62257 first introduces a methodology for implementing rural electrification using autonomous hybrid renewable energy systems. Secondly, it provides a guide for facilitating the reading and the use of the IEC 62257 series for setting up dec

44、entralized rural electrification in developing countries or in developed countries, the only difference being the level of quality of service and the needed quantity of energy that the customer can afford. The IEC 62257 series is designed as follows: Parts 2 to 6 are methodological supports for the

45、management and implementation of projects. Parts 7 to 12 are technical specifications for individual or collective systems and associated components. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its applica
